\caption{The 7-injection episodes model parameters. The injection 
energies $E_1$ to $E_7$ are in units of $E_0$, the initial energy. 
Other model parameters are: the initial Lorentz factor $\Gamma_{0}$, the 
ambient density $n_{0}$, the half opening angle $\theta_{0}$, the line 
of sight angle $\theta_{\nu}$, the electron energy index $p$, the fraction 
of internal energy stored in electrons after acceleration $\epsilon_{e}$ 
and the fraction of internal energy stored in the form of magnetic field 
$\epsilon_{B}$.
